OLIVER W. BARTLOW AND RANSOM AULT, OF OMEGA, INDIANA, ASSIGNORS TO SAID BARTLOW.

TIRE-COOLING TRESTLE.

SPECIFICATION forming part of Letters Patent No. 241,778, dated May 24, 1881. Application filed October 11, 1 880. (ModeL) To all whom it may concern:

Be it known that we, OLIVER W. BARTLOW and RANSOM AULT, of Omega, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in TireCooling Trestles; and we do hereby declare that the following is a full, clear, and

. exact description of the invention, which will en. ble others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Fig. 1 is a view, in perspective, of a tire-coolin g trestle embodying ourimprovements. Fig. 2 is a side elevation of the machine, the frame being tilted and the rim of the wheel projected into the water-trough. Fig. 3 is a rear elevation of the machine shown in the position last above-described, and Fig. 4 is a sectional detail view.

This invention has relation to tire-cooling trestles; and it consists, in the improved features of construction and combination hereinafter fully described, and particularly pointed out in the claims.

Referring by letter to the accompanying drawings, A designates a longitudinal frame composed of the horizontal pieces B B and the transverse pieces 0 G 0 placed thereon and secured together by bolts D, passed down through metal strips E E, resting on the crosspieces 0 G and fastened to place by screwbolts D and nuts F.

G designates a transverse frame composed of the longitudinal pieces H, and the transverse pieces 11 bolted to the under sides of the pieces H. Lateral movement of frame G is prevented by bars Z bolted to the under side of the bars H, and between the bars B B of frame A, as shown in Fig. 3, the pieces H'H coming between the pieces B B and the metal strips E E of the frame A.

The frame A is pivoted between the upper ends of the legs J, the feet of which are let into a sillior cross-piece, K, to give them stability. The rear end of the frameAis provided with a hinged lever, L, which also serves as a leg for that end of the frame A.

The frame G is provided at its middle with the metal arch M, from which a spindle, N,

rises. From the lower side of the arch M an eye, 1?, projects, and a rod, Q, connects this eye P and the lever L. From the rear or upper piece, H, of the frame G a spring, R, having a handle, S, extends rearward and engages, when the machine is operated, with catches T T projecting from the inner face of one of the pieces B of the frame A. The frame Gis intended to slide in the ways formed by the strips E E and pieces B B of the frame A.

U represents the water-trough, which is to be set in the ground, its mouth being even with the surface of the same. The trestle is to be set near the trough, so that when the frame A is tilted the frame G may slide down in the ways in the same and carry the rim of the wheel into the trough.

The operation of the device is very simple and is as follows: The wheel is placed upon the spindle, the dish side of the wheel being down. By then grasping the hinged lever L and elevating the rear end of the frame A the front part of the frame A will approach the water-trough, and while this is being done the spring It should be disengaged from the upper catch, T, and theleverL depressed to cause the frame G which carries the wheel to descend in the ways in the frame A and permit the rim of the wheel to enter the water, there to be revolved to extinguish the burning felly and cool the tire. The plates VV on the frame G, and the strips E E on the frame A prevent the heated tire from burning the frames A or G.

By this device a set of tire can be put on in about one-third of the time required to put them on in the ordinary way.

The device is simple and inexpensive, and its usefulness over the ordinary method of cooling tire is so obvious as to need no comment.

Having thus fully described our invention, what we claim as new, and desire to secnreby Letters Patent of the United States, is-

1. In a tire-cooling trestle, the combination of the tilting frame A, and the sliding frame G mounted thereon, and adapted to carry the wheel to be treated, with the lever L, hinged to the frame A, and the connecting-rod Q, arranged between the lever L and the sliding frame, as shown and described.

2. In a tire-cooling trestle, the frame A, our own We have hereto affixed our signatures pivoted between the legs J, and having the in presence of two witnesses.

strips E, hinged lever L, and catches T T, in OLIVER W BARTLOW combination with the frame G, provided with RANSOM AULT.

5'arch M, carrying the spindle N, and eye P,

the spring R, having handles S, and the rod Witnesses: Q, substantially as specified. J A0013 REITZEL, In testimony that We claim the foregoing as J. J. EDWARDS.
